Clear skies and temperatures in the mid-30s are expected to help solar car teams reach speeds of more than 100 kilometres per hour as they drive through northern South Australia today.

There are still 36 cars in the World Solar Challenge heading from Darwin to Adelaide.

One vehicle was engulfed in flames after its battery exploded on Tuesday.

The Filipino team was stopped at Tennant Creek when its car's battery blew up.

No-one was injured but the car was destroyed.

An solar event organiser, Judi Lalor, says the leading team from Japan's Tokai University has the only car which had crossed into the South Australia by the end of Tuesday's racing.

"But you have very strong competitors not too far behind. We're still only just past the halfway point and so there's a lot of kilometres still to travel," she said.

"This is an event about distance and endurance, it's not just about, you know, necessarily the fastest teams and really anything can still happen.

"We're talking about unforgiving terrain, we're talking about there could be wildlife, massive road trains were actually heading up the Stuart Highway. There are bushfires, there's the elements ... the teams are certainly in for an adventure."

You have no doubt been hearing a lot about the Paris Agreement and know that it pertains to climate change, but are too embarrassed at this stage to ask for an overall explanation of what it's all about.
